Adraxx 81028EHK Electronic Components Electronic Hobby Kit

Serial port Bluetooth, Drop-in replacement for wired serial connections, transparent usage. You can use it simply for a serial port replacement to establish connection between MCU and GPS, PC to your embedded project and etc. HC-05 has be designed Master or Slave when the factory, user couldn't change the role. Bluetooth protocal: Bluetooth Specification v2.0+EDR Frequency: 2.4GHz ISM band Modulation: GFSK(Gaussian Frequency Shift Keying) Emission power: ≤4dBm, Class 2 Sensitivity: ≤-84dBm at 0.1% BER Speed: Asynchronous: 2.1Mbps(Max) / 160 kbps, Synchronous: 1Mbps/1Mbps Security: Authentication and encryption Profiles: Bluetooth serial port Power supply: +3.3VDC 50mA Working temperature: -20 ~ +75 Centigrade Dimension: 26.9mm x 13mm x 2.2 mm Usage: After pairing only need as fixed baud rate of the serial port as can be, so long as it is "fixed baud rate, 8 data bits, no parity" serial communication format equipment can be a direct replacement for the original wired serial port without the need to modify the program. Such as data acquisition, smart car, serial printer, outdoor lattice strip screen control.Paired with computer use: for computers and devices via Bluetooth serial communication, use serial paired with the phone use: suitable for the mobile phone with the device through Bluetooth serial communication, use serialpaired with the Bluetooth host: for the two devices directly through the Bluetooth serial communication between the microcontroller and the microcontroller wired serial interface with microcontroller between use with serial
